My 7.3 has a hard start in cold weather. It has 297,600 miles. It cranks but misses and lopes. Once I hold the pedal to the floor it clears right up. After talking with several Ford techs it is clear my injectors are wore out.

As for running 5w synthetic, thst is the stupidest idea I have ever heard. That engine is meant for 15-40. Fix the problem. Dont adjust to the problem

You have inj(s) bad. If it clears up after a couple of minutes. If it does not clear up it leans more to the idm.You need to run a cyl contribution test when it is stone cold. To do that you will have to have a scanner with that feature and unplug the temp sensor and plug a resistor in to the wire to make the scanner think the engine is up to temp to complete test.

Spoken from a guy who lives in TX

The OP is in Wisconsin, you guys live in different worlds, your trucks exposed to different definitions of the word "COLD"......

What is UVCH?

I have replaced 4 injectors, all gp's, fuel pump, fuel filter and tank filters. I went from running rough in am when cold to barely running at all. I could not go over 10 mph. I replaced fuel filter yesterday morning, i drained the fuel out of the filter housing. It was in the low 40's here in south Florida. I tried to start and was like starting on 3 cylinders. So I plugged it in and waited 2 hrs. It started right up. About 2 min later I reved it up a little and back to running on 3 cylinders. (could be more, just runs very very rough).

I was told that the PSD has a water seperator. I thought it was in the fuel filter. Is this true. Where does the water go after seperated? I use diesel 911 additive every few fillups. Is this too much or too little?
Thanks

My 2000 7.3 also has a hard cold start problem that developed all of a sudden and with no codes. anything below 50 F It cranks great but cranks for way to long before starting. When it starts it runs great no misses or rough idle its smooth as can be and the rest of the day it starts great. I've got new batteries, glow plug relay, and fuel filter the glow plugs resistance is with in specs not sure what else to look at I am kind of lost I would appreciate any help I can get.

It won't have codes usually for hard starts.
How long is 'too long?' It's a very subjective amount.

I pulled mine into the garage to do a air filter change a couple weeks ago and I wouldn't start 10 minutes later tried again it fired right up. Ran normal , sat over night same thing no start, i figured it was a CPS and it was all is good.

Has it been always hard to start or very sudden like mine, I'f it's sudden try to swap out ur CPS

If the rpm gauge (tach) don't move while it's cranking the CPS is gone. I usually see mine move right before it fires up. Have you run some power service
